Description
Technical Field
Embodiments of the present invention relate to, but are not limited to, computer technology, and in particular, to a ticket requesting method and apparatus, and a computer readable storage medium.
Background
With the development of high-speed rail and passenger transport, great convenience is brought to the trip of people, people buy tickets through a plurality of different channels such as 12306 websites, mobile phone clients, telephones, self-service machines and the like, and the situation that one ticket is difficult in the past is gradually changed. However, in the current train and car running systems, the following problems still exist:
1) Every time a passenger flow peak appears in holidays, tickets are still a scarce social resource, various ticket robbing systems are inoculated to generate, so that the resources are not reasonably distributed, and meanwhile, bad phenomena such as ticket pouring and vending exist.
2) The passengers cannot timely understand the state of the vehicle. For example, if a shutdown, a change line, or the like occurs before a departure, a passenger needs to log in a message issued by an official authority to know the situation, and the situation of missing the message is easy to cause. For another example, in the running process of the vehicle, passengers and passengers receiving the vehicle cannot know the running state of the vehicle in time, and if the conditions such as late time occur, the passengers and the passengers receiving the vehicle cannot change the journey and the plan in time, so that time and property losses are caused.
3) And adding a random number into the first request, so that replay attack on the ticket processing device or system is effectively prevented.
In summary, how to reasonably allocate and utilize ticket resources and improve the utilization rate of the transportation system is an urgent problem to be solved in the ticket operation system.
